Patented r c. 12, 1907.

Application filed January 81,1906. 81511411110138.1102.

To all whom it may concern:

Be it known that I J ESSE JEREMIAH TROE- GER, a citizen ofthe United States, and a resiand a device for varying speed.

The principal objects of the invention are to provide for obtaining the same number of different speeds in both the forwardv and reverse motion with the use of fewer gears than are ordinarily u'sedin devices of this character; also, to provide a device which will give an additional speed in both directions by the simple addition of two gears; also, to so construct a device that ,all the gears can be lubricated.

' Further features and advantages of the invention will appear below.

Referenceis to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a horizontal sectional view on the line 1 1 of Fig. 2, showing most of the parts in plan and illustrating one embodiment of my invention. Fig. 2'is a sectional view of the same on the-line 2 2 of Fig. 1. Fig. 3 is a sectional view on the line 3 3 of Fig. 4. Fig. 4 is a sectional view on the line 4 4 of Fig. 3, and Fig. 5 is a plan of a guideplate for the operating-levers. p

I have shown a shaft 10, from which power is transmitted through a pair of clutch members 11 and 12 to a shaft 13. The clutch members 12 are operated by a slide 14, which is operated by a yoke mounted on a bellcrank 15. It will be readily understood that the manipulation of this slide-will connect and disconnect the shafts 10 and 13 in a manner which is common. The bell-crank is connected by a link 16 with an operating lever 17. Thiso crating-lever is pivoted on a. pair of ears 18,.w 'ch are mounted on a collar 19, rotatably mounted on a hub 20, throu h which the shaft 13 passes. (Jonsequent y the operating-lever is capable of motion in two directions about the two pivots formed in the cars 18 and on the shaft 13; When it moves on the pivot 18 ,the bell-crank W'lll not be affected, but when it moves at right anles to the shaft upon the latter as a pivot the ever is operated in an obvious manner.- The hub'20 is mounted upon an oil-tight casin 21, through which the shaft 13 passes, an

' which is designed to contain most of the op-- crating parts of the transmission mechanism. It will be understood that this casing is intended to contain oil inwliieh the various ears can run. The power-receiving shaft 13 1s designed to transmit power to a shaft 22,

which transmits the. same to any desired machine or set of machinery For transmiting thepower directly a gear 23 is mounted on the shaft 13, and it meshes with a gear 24 on the shaft 22. In order to change the s eeds from the ordinary s eed which won d be mechanism is emplo ed: The gear 23 is transmitted in this E anner, the following mounted on a sleeve 5, which is capable of rotatingon the shaft 13. This sleeve is provided with a notch 26, in which is ada ted to engage. a tooth 27 on a collar 28, w 'ch is fixed to said shaft. The sleeve 25 is providedwith a peripherally-grooved collar 29,

with which a yoke30 engages. T his yoke is connected w1th a rod 31, which projects through the casing 21 and which is pressed outwardly by a spring 32, so as to normall hold the sleeve in such osition that the toot 27 will not eng e in t enotch 26, and power transmitted to the shaft 13 will therefore not be transmitted throu h the gear 23 directly. When, however, the lever 17 is in the osition shown in Fi 1, a pin 33, which sli es in a bearin -34, rlgidly connected with the frame, W11 be forced outward] against the tension of a spring 35, and a 1'0 er 36 on this pin engages an inclined surface 37 on an arm this stud is also connected another arm 40, which is in turn connected'with the rod 31.

It will be seen that the bell-crank formed by the parts 38, 39, and 40 is operated by the pm 33 in such a manner that when the ever 17 is'in the position indicatedthe rod 31 is forced inwardly, and the sleeve 25 assumes the position shown in Fig. 3. This is a posi tion' of the lever 17 in which the 4 ower is transmitted from the shaft lfl to t e shaft reg;

. medium position, in,which'the power is trans- 13 through the clutch, and it is obvious this .ing gear on the shaft 13. The" yoke connected with aslide 50. This'slide power is then transmitted .to the shaft 22 at a medium rate of speed produced by the relative sizes of the, gears 23- and 24. For the purpose of varying this speed the shaft 13 is provided with another pair of gears 41 and 42 of diflerent. diameters, and a' shaft 43 is provided parallel with the shaft 13 and hav-.

through thecasing 2 1 and is connecte byia link 51 with the lever 17. The sleeve. 47ris mounted on a key 52 on the shaft-'43. "The operation of these parts will be readily understood.

As has been indicated, the lever 17 can be moved on the pin running throughthe ears 18, as a pivot, and is shown in Fig, l'in its fioor 7,2.

mitted to shaft 22 at a medium rate of speed.

When, however, this lever is pushed either to the right or left, the roller '36 will be disen gagedfrom the surface 37 on account of the operationof thespring to force the pin 33 backwardly, and the spring 32 will operate to withdraw the sleeve 25, and so prevent the transmission ofmotion from the shaft 13 to the shaft 22 through the gears 23 and 24. One of the gears 44 or 45, however, will be moved into mesh with its corresponding gear or pinion on the shaft 13 by the opera- 7 tion of the link 51 and slide 50. Come quently rotation will be imparted to the shaft 43 at either a higher or lower rate of speed than that of the shaft 13. The rotation of this shaft retransmitted to the gear 46 on account of a key'52,'which is mounted thereon and which engages the gear. Motion is then.

transmitted from this gear through the gear 23, which rotates freely with respect to the shaft 13, to the gear 24. This modification of the speed'may take lace without an T this gear is moved longitudinally a pair of flanges 53 on the gear 46 will be engaged by which 0 erates to transmit. motion to the longitudinal motion of t e gear- 23; but 1f the gear 23, and the gear 46 will move with 1t along the keyway 52. This provides for giving three speeds to the'driven shaft, and

I will now describe the reversing mechanism,

driven s aft at three different rates of speed also. On a shaft 55 is mounted a doublefaced gear or pinion 56, which is capable of meshing with both the gears 23 and 24. Connected with the gear 56 is a slide 57, which is in turn connected with a rod 58, this rod being operable by a link 59 and bell-crank 60.

swing about 'a rod 64 as a center.

slide. and; thev lever 62 is provided with a slot 70, by-means of which it is pivoted on a rod 71. This'rod is mounted in a stationary position one; frame 72, which may represent the cab for. receiving a latch on the lever.

This bell-crank 60 is connected by a link 61 with a reversing-lever 62. This lever is pivoted on a collar 63 on the frame 21, so as to The collar is also provided with aprojection 65, through which a pin 66 asses, on which the lever is also pivoted. T e in 66 and 'rod 64' are at right angles-to eac other. On the rod 64 is a yoke 67, which engages a collar 68 on the gear 23'. The sleeve 25 is provided-- with a key 69, along which a gear and collar The collar 63 is fixed to the rod 64,

of a'motoracar or the floor of a vehicle of any 'kind. It will be seen, therefore, that the lever 62iscapable' of pivotal motion on the rod 71 to move the shaft 64 and that 1t is ca-. pable of pivotal motion on the shaft 64, in

whichthe lever slides along. the rod 71, the 1 latter passing through the perforation or slot 70. p

In Fig. 5 I have shown a plate 73 over the In this plate are passages for the levers 17 and 62,. A passage 74 for the former is provided with three offsets 75, 76, and 77 A passage 78 for the lever 62 is p'rovided with'an offset 79. Each of these assages and offsetsis provided with a notcI 80 t is thought that the. operation will be obvious. When the lever 17 is in the position shown in Fig. 1, in which speed is transmitted to the shaft 22 at a medium rate, it is in the offset 76, and when pushed from the? slot 74 into the offset 76 the bell-crank 15' is manipulated,

from the pin 33, so that: the spring on the lattercan withdraw it from engagement with the arm 38,,so that'the spring 32 can draw out the rod 31 and disconnect the shaft 13 from the sleeve 25,- as has been explained. The lever is then pushed either to the lighter left along the slot 74, which through the operation of the link 51 brings either of the gears 44 or 45 into engagement with its companion gear on the shaft 13. Then the lever; is

moved into the slot 75 or 77, as the case may be,- which couples u the shafts 10 and 13 again and provides or transmitting motion IIC to the shaft. 22, either at a decreased or increased rate. Reversal can be had at any of the three speeds by manipulating the lever 62 in the slots 78 and 79 in a similar manner. The movement of the lever 62 on the rod 71 as a pivot moves the rod 64 and the gear 23,

so as to bring the latter into mesh with the gear 56, as is indicated in dotted lines in Fig.

3. The pivotal movement of the lever 62 on the'rod 64 forces the gear 56 in the other direction until it meshes with the gear 24. In this position the gears 23 and 24 are out of mesh with each other. As the sliding of the gear 23 is relative to the sleeve 25, it will be obvious that the manipulation of the speedchanging lever 17 will be performed inthe san'ie manner as before and that three speeds in the reverse direction can thus be obtained. By this construction six speeds in all are obtained with a minimum number of gears, while the operating means is very simple, being controlled entirely b one reversing-lever and one speed-changing lever. Furthermore,

the gear 56, which is used in reversing, is out of engagement with the other gears when it is not in operation, and therefore is not subject to wear and it does not consume power except during reversal. By the provision of the oil-tight casing and the proper location of means for preventing the oil from passing through the bearings upon which the shafts and sliding rods are located a most efficient system of lubrication is provided. It will be further seen that in order to provide one or more additional speeds it will only be necessary to add two gears to the device,'one on,

the shaft 13 and-the other on the sleeve 47, for each additional speed desired, and, furthertllerin'ore, that such speed will be available for use inboth forward and reverse directions.
